Retrieve dynamic data using Python

Hi, Is there an API function that retrieves generator angles, speeds, etc., in the PSSE dynamic simulation using Python? I am able to retrieve the bus voltages using : ierr, voltages = psspy.abusreal(-1, string="PU")

I wonder if there is a similar way to extract dynamic states. Thank you

Select channels for the wanted information and use psspy.chnval to get the value.

Thank you so much. chnval reads the states. However, I am using psspy.chsb(0,1,[-1,-1,-1,1,1,0]) to select channels and don't exactly know how to point at the certain generator state.

What do you mean? I don't understand.

Do you possibly have a sample Python code that uses channel selection for generator states and chnval to get their values? Thank you in advance.
